Aside from that rather cool addition, today's update for Chrome includes "a number of bug fixes and performance improvements", which is pretty much standard practice for all Chrome updates. It should be available to download for all supported Android devices from the Google Play Store over the next few days.

If you're using Chrome for Android version 40 or older it is Vulnerable. https://freakattack.com/clienttest.html
I use the Beta desktop version and was on v41 when I tested a few days ago and it was safe but I have seen reports of Chrome v40 being vulnerable on W7 x64 but can't verify that.

I wish the engineers would start over with Chrome and build it (optimize it) from the ground up. The current build sucks system resources like no other, and no amount of OS optimization can fix that. It needs a complete code overhaul to run light and fast.
